Radiation Oncology

Radiation therapy uses high-energy radiation to damage cancer cells' DNA and destroy their ability to divide and grow. It is delivered using linear accelerators, proton accelerators, metered cobalt-60 exposure, or brachytherapy where radioactive seeds are placed inside the patient on a temporary or permanent basis to kill cancer or relieve pain. The main radiation oncology society and annual conference is the American Society of Radiation Oncology (ASTRO).

Targeted radionuclide alpha therapy study wins SNMMI's Abstract of the Year

The study touts the benefits of targeted radionuclide alpha therapy for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who have not had success with other treatments.

High-intensity focused ultrasound effectively treats PCA, reduces side effects

Men with prostate cancer can avoid many of the unpleasant side effects of chemo, surgery and radiation therapy when they are treated with high-intensity focused ultrasound instead.
